Presentation Transcript

  1. November 9, 2012 Common Core: Are we ready?

  2. Bell Work Write 3 equivalent fractions for each: • 4/5 • 5/4 • 2.8 • 9/15 Be ready to use math language to explain your thinking.

  3. Norms • Participate positively • Share the air time • Silence phones • Seek clarification

  4. Outcomes • Examine our conceptual understandings of operations with rational numbers and what that means for instruction at multiple grade levels • Explore Smarter Balanced Assessment Consortium rational number items • Develop an understanding of the CCSS Mathematical Practices in the context of teaching operations with rational numbers • Identify student misconceptions and strategies for support.

  5. Importance of Equivalence • Why is equivalence of fractions important? • What are some common misconceptions kids have when making equivalent fractions? • How can we support learning for students who hold these misconceptions?

  6. Planting Flowers (Addition and Subtraction)

  7. Reflecting on Planting Flowers • What will students need to understand to make sense of part a? • What if a student says that impatiens are 1/9 of the garden? • How does the idea of equivalent fractions come into this problem? • Which of the CCSS math practices would best support this problem?

  8. Break

  9. Visualizing Addition and Subtraction

  10. Reflection • How could having students make drawings to justify addition and subtraction with fractions help students with common misconceptions? • How is this activity connected to the “Planting Flowers” problem? • Which of the CCSS math practices would best support this problem?

  11. Article: The Power of Problem Choice • Sentence • Word • Phrase

  12. Lunch

  13. Most Important Point

  14. Teaching Multiplication of Fractions • Individually, answer the questions on the handout. • What do students first need to understand about fractions in order to make sense of multiplying fractions • Why do we say that “of” means “times” when we think about multiplying fractions?

  15. True/False Activity Decide if each statement is true or false. • If it is true, justify your answer. • If it is false, show why it’s false and revise the statement so it is true.

  16. Reflection • How did these exercises help you think about the concept of multiplying fractions? • The intention was to begin to develop students’ strategies to reason about multiplication for fractions. How does this activity support the ideas in the CCSS regarding learning fraction multiplication?

  17. Break

  18. Multiplication Models • Independently answer #1-4 • Discuss answers in group. • Which was least challenging? • Which was most challenging? • What was the impact of having to estimate, draw a visual and write a number sentence?

  19. Student work analysis What error has the student made? What would be your next steps with this student?

  20. Team Thinking Time Where do your students tend to struggle with fraction concepts? What fraction operation concept might be most important to address in your district?

  21. K-12 Connections How does each grade band support students in understanding this concept?

  22. SBAC sample items • 3-5 Fractions 2a & Fractions 2b • 6-8 Expressions and Equations 2 • HS: Rationals and Radicals

  23. Please Provide Feedback Click the feedback link on the Moodle to provide us with feedback on today’s PD. If you are getting SCECH’s (formerly known as SB-CEU’s) you will receive a separate email from MDE to complete a survey.
